Consider adding imenu support

[DamienCassou]

It would be nice to be able to use imenu in magit buffers:

• in magit-log, imenu could let the user go to a commit rapidly by hash or description
• in magit-rev, imenu could let the user go to a file rapidly by filename
• in magit status, imenu could let the user go to a section rapidly

That would be nice, and implementing it might actually help me use imenu more (in other contexts). But it's not a high priority.

[tarsius]

Is there anything else you want to add, or can we close this?

[DamienCassou]

We could add it to git-rebase-mode too, I forgot it. What do you think?

[tarsius]

Feel free to do that if/when you have time to do it. Eventually someone will ask for it, so why not add it sooner rather than later.

A few other candidates:

• magit-refs-mode

• magit-diff-mode and magit-stash-mode

  I think it'd make sense to define a single set of imenu functions
  for diff/revision/stash buffers, setting these functions in
  magit-diff-mode rather than magit-revision-mode.
  magit-revision-mode and magit-stash-mode would then inherit
  these from magit-diff-mode.

• magit-reflog-mode and magit-stashes-mode

  Right now, these inherit the log's imenu functions, which don't
  return useful results. If the regexp of the log's imenu
  functions aren't easily extended to work with these, I think
  these mdoes should have their own imenu functions or should at
  least set the imenu functions to nil.
